Product Brief Description
The GE 369B1874G5002 is a Digital Output Base (BDO11) with 16 relay outputs. Similar to other base modules, it provides the physical connection between a controller’s I/O pack and external field wiring. This specific version is designated as a “Relay Board” and is designed to handle switching of a wide range of external devices, making it a flexible component in industrial control systems.
Detailed Product Description
This module serves as an essential interface component, typically mounted on a DIN rail within an industrial cabinet. It provides the terminal points for connecting 16 discrete output devices to an I/O pack. The “Relay Board” designation indicates that it uses mechanical relays to switch the outputs, providing electrical isolation between the low-voltage control circuitry and the higher-voltage loads. This is a robust and reliable method for controlling various types of equipment. The BDO11 designation suggests it is a specific variant within the Digital Output Base family, likely with a different form factor or set of electrical characteristics compared to the BDO10.

Functional Role in a System
In an automation system, the 369B1874G5002 receives digital signals from a controller’s I/O pack. When a signal is received for a specific channel, the corresponding relay on the base module is energized, closing its contacts. This action connects the power source to an external device, such as a solenoid or a motor starter, turning it on. The physical separation and isolation provided by the relays are crucial for protecting the sensitive control electronics from voltage spikes and noise originating from the field devices.
Common Applications
The versatility of relay outputs makes this base module suitable for many industrial applications:
- Process Control: Actuating valves, pumps, and other devices in a sequential process.
- Machine Automation: Controlling motors, clutches, and brakes in manufacturing equipment.
- Building Automation: Switching on/off lighting, alarms, or other systems.
- Safety Circuits: Interfacing with emergency shutdown systems where electrical isolation is a key requirement.
